ttyplot:tldr:4d925
This command is a combination of multiple commands executed together to continuously plot random numbers on the terminal using ttyplot.
Let's break down the command step by step:
-
The command starts with a while loop:
while ${true}; do
. This creates a loop that will continue indefinitely since${true}
always evaluates to true. -
Inside the loop, the command
echo ${$RANDOM}
is executed. The$RANDOM
variable in Bash holds a random number each time it is accessed. Therefore, this command echoes a random number to the terminal. -
After echoing the random number, the command
sleep ${1}
is executed. Thesleep
command simply waits for a given number of seconds before executing the next iteration of the loop.${1}
refers to the first argument passed to the script or command. -
Finally, the loop is closed with
done
. -
The output of the loop, which is the randomly generated numbers, is piped (

) to thettyplot
command.ttyplot
is a tool used to plot data in real-time on the terminal.
Overall, this command continuously generates random numbers using the $RANDOM
variable, waits for a specified period of time using the sleep
command, and then plots the numbers in real-time using ttyplot
.
